Abstract
Substances such as dyes, drugs, condiments, flavors, aromas, chemicals, vitamins, adhesives, and the like are provided as encapsulated within the cells of microorganisms. Microorganisms such as yeasts, fungi, molds, and protozoa are grown in a medium so as to promote the formation of biological capsules, such as by forming relatively large globules of fat within the cell wall. A substance such as a dye, a drug, a condiment, a flavor, an aroma, a chemical, a vitamin, an adhesive, and the like is passed through the cell wall of the microorganism and into the biological capsule thereby producing an encapsulated product.
